downgrading the kernel

We have installed RHEL 3 which is having kernel version 2.4.21-32.EL and this is not supported by Oracle Apps 11.5.10. We have to downgrade it to kernel version 2.4.21-20.EL. Getting dependecny error while executing RPM -e. Please advise how to replace the kernel verson 2.4.21-32.EL with 2.4.21-20.EL.

First we tried to uninstall the kernel which gives error "Share file violation" therefore we tried to install the downgraded version of kernel directly which completed with warning. But still it is showing the higher version only. We are using following command to check the version.
rpm -qa | grep kernel

You have mentioned in your mail to choose the downgraded version. could you please guide me to choose the required version.

since you want to downgrade your kernel which is the core of an
y OS(here Linux) its quiote obivious that you need to meet a lot of depende
ncies, since the other packages will require the higer versions of themselv
es and/or kernel too. So in my view I would suggest to go with fresh instal
lation with the older kernel or else you could also try to install 2.4.21-2
0.EL kernel and had two different kernel to work with but it will have its
own issues... I think so.

Thanks for the reply. We installed the lower version too which completed with warning. But when we check the version using grep command it is showing only for the higher (earlier) one.how can i assure that both version of kernels are installed.Please advise.
